<p>The assembly for the biological processing of sewage, especially, has at least one fixed-bed body in a basin formed by a number of cube-shaped filling body blocks which are brought together. At least part of the fixed-bed bodies (54) are suspended in the basin (21). At least part of the fixed-bed bodies (54) are suspended from a carrier/lifter system, so that they can be inserted into the basin and lifted out of it. All or some of the fixed-bed bodies (54) are held in release mountings at the carrier and/or lifter. The blocks for the fixed-bed are composed of a number of identical body components which are deployed longitudinally and laterally in neighboring columns (55) of assembled blocks (28) over each other within the basin (21). Each column (55) has its individual suspension mounting at the carrier/lifter system. All the columns (55) can be lifted out of the basin (21) and lowered into it simultaneously. The lifter/carrier system has a two-dimensional frame structure with a number of bonded lateral (57) and longitudinal (58) carriers. All the columns (55) of fixed-bed blocks are suspended from the lateral carriers (57). The columns (55) are supported by carrier rods (62) through them, with a plate at the bottom as a laying surface for the under side of the lowest block (28) in each column, and give the supporting surface for at least four of the adjacent and center netting tubes (31) which form at least a part of each block (28), and which are set back from other outer netting tubes The netting tubes are centered at their carriers by guide tubes at horizontal centering plates as spacers. Retainer beams prevent flotation of the fixed-bed bodies in the basin, using their weight to keep them submerged, with spacers as netting tube sections (53).</p> |
